Application. filed August 8, 1911. Serial iN'o. 643,000..

To all whom it may concern: p

Be it knownithat I, OscAmS. WINKLER,.\ citizen of the United States, residing. at Baltimore city, State of ?Maryland, have invented new and useful: Improvements in Spoke-Extractors,of which the following is a specification.

This invention pertains to certain :novel and useful improvements in I spoke 6X-. tractors, and has particular application to a device of the class described; adapted for readily: and quickly removing the spokes from the hub of a wheel.

In carryinglout my invention, it ismy purpose to provide a spoke extractor which will embody thedesired features of 1 simplicity, durability and efficiency and,i furthermore, I aim to provide a device which may be easily and quicklyplaced position on the spoke to be removed, and then o'perated by asingle movement of a handle to withdrawtheispokefrom. the socket in the hub. i

With the above-recited obj ects,a and other of a similarnature in view, the invention arrangement of parts, set forth in and falling within the scope of the appended claims.

In .the accompanying. drawing -Fignre 1 is a view in side elevation of a device embodying my invention, showing the same in position for theremoval of alspoke from the hub. Fig. 21s a front lVlGWOf the hub engaging; member and the ,supporting; stirrup of the spoke extractor. Fig.:3 is a similar.

view of the spoke 1 clamping; mechanism forming a support and bearing for the operating handle which is pivoted to the hub engaging member. Fig. 4 1 is a perspective view of the cam lever. Fig. 5is a one end of the handle. Fig. 6 is a vertical sectional view through Fig. 3.

Referring now to the accompanying ,drawingin detail, the numerall designates the.

hub ofa vehicle wheel or the like and2 indicates one of the spokesthereofa My improvedi spokeextractor, as shown in the drawing, comprises ahub engaging member 3, which is in the nature of a :bar.

her 3 are the arms 55, suitably spaced fra mentary longitudinal sectional View; through Connected to 6--6 therein for the reception of theibolt 17, the shank portion of the bolt: extendingbetween the: two arms carrying the. bearing;

roller 8.

It will be seen that by providing a plurality ofbores alongthe arm, I form bear-1 ings by "means of which the roller and: its shaft orsupportingpbolt may be adjusted to accommodate spokes of various sizes.

The arms, together with the bearing roller form a stirrup for the reception of the spoke,

as is shown in Fi 1, whereby thespokei extractor may be he d in its applied position.

The numeral 9 indicates a bifurcated cam Patented Apr.15, 191l3.

apart and: having transverse aliningbores 10-10 for; the purpose hereinafter de-- scribed;

The numeral 14. designates a frame com prising the side bars .15-.-15 and thecross bar 16, said frame being, designed to be moved along the spoke to be extracted.

The side bars 15 are each. longitudinally 1 slotted met :16 to form guide ways for the sliding head or block which is actuated by means of the rotating screw. shaft 18,3

which is threaded. into: the bore 19 in the cross bar 16, said screw shaft being provided .with a crank or handle 20 by means of which it is :actuated. At the upper .ends. of the sidebars 15-"-15 of the frame is a cross shaft 1 21 carrying a bearing roller 22 and segment shapedspoke engaging spurs 23, while 24- -24: 1

arosmall rollers one ateach end of the cross shaft 21, said. rollers beingadaptcd to form a bearing for the contacting surface of the cam jaws, as is shown in Fig.1.

From theabove descrlption, taken in connection with the accompanylng drawings,

the construction and. manner of employing. my improved spoke extractor willbe readily apparent. When the spoke is tobe extracted, the device is" assembled thereon as is shown in dotted lines in Fig.1 sothat the socket :of. the member 3 fits against the hub, while the roller 8 carried by thearms depending from the socket members is arranged below the spoke. The frame 14 of i the clamping and bearing member is then shifted along the spoke, until the roller 22 projects upward "between the two 'jaws of the cam member and contacts with the tongue 13', one of the segment shaped spurs engaging with the spoke, while the spur.

or-ipoint of the block 17 bears against the opposite side of the spoke, this vbeing. accomplished byrot'atin'g the screw shaft through the crank or handle 20 thereof,- which forces the block; and spur into contact with the adjacent sides of thespoke's It willbe seen that thesspoke is engaged by r the spurs, and

- theirame 14 is securely clamped'thereon;

the roller 22 bearing against the. tongue 13.: The spokes may now be extracted by push ing "downwardly 0111 the handle" 12 which causes the'cam to bear. against the roller 22 and the heel of the cam'to bear against the 1. Aspokeextractor comprising a member adaptedilto bear against the hub carrying the spoke, a spoke supporting member rollers so that when the handle is ope fer'ated the spoke is withdrawn from the.
